3. Ensure the preventative maintenance requirements,

on pages 12 and 13 of this manual have been met.
Inspect the wire rope and winch and repair any
defects before operating the winch.  

4. Ensure operators are trained and understand the 

General Safety Recommendations section of this 
manual.

5. After the hoist/boom is properly positioned, we rec-

ommend the operator slowly pay-out, then haul-in a
short length of cable.  The winch should perform
these operations in a smooth and controlled manner.
If the hoist does not operate smoothly or makes any
unusual sounds, the source of the problem should be
identified and corrected before any attempt is made to
lift the load.

6. When lifting loads, we recommend the following

steps:

•

Slowly pay-out wire rope from the hoist drum 
until it reaches the load.  

•

Securely fasten the hoist cable to the load and 
be sure all ground personnel are a safe distance 
from the load.  

•

Slowly lift the load a short distance and stop.  A
small amount of "bounce" may be observed, 
depending on the weight of the load, size and 
type of wire rope, and the amount of boom ex-
tension. 

•

Allow the load to stabilize then watch for any 
signs of downward movement of load or any 
cable drum rotation.  The winch static brake 
should hold the load in place without allowing 
any downward movement.

•

If the load creeps down or there is any move-
ment of the cable drum, the load should be low-
ered to the ground immediately and the source of
the problem identified and corrected.

•

If the winch is holding the load securely, proceed
with normal operations in accordance with the 
equipment manufacturer's operating procedures. 

7. The air motor should not be allowed to race when

lowering heavy loads.  Always operate within the
speeds given in the sales brochure.
